Title: Speed controller of induction motor
Inventor: YAMAGUCHI HIROSHI
IPC: H02P23/07
Filed: 1984-02-15
Abstract: PURPOSE:To stably control the speed by measuring the speed when the speed is stabilized and varying the firing angle at every certain interval on the basis of the measured result. CONSTITUTION:A microcomputer 3 counts a rotating speed signal B, compares it with a speed set signal C, delays the phase at the phase decided by the timing of the zero point detection signal A of a commercial power source, and outputs a signal D. The signal D is transmitted to a solid state relay 8, thereby controlling an induction motor 9. Since the count of the rotating speed signal B is unstable during the prescribed time from when the phase angle is altered, the counting is not executed, but the counting is performed after the prescribed time from the speed is stabilized to detect the speed of the motor.

Title: Method for detecting and controlling position of ram of highspeed punch press machine and its apparatus
Inventor: OSUKAA AIGENMAN
IPC: B30B15/00
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To decide a position of a ram at a lower dead center without any measurement by adjusting the height of a ram at which it arrives again at a predetermined position in the case that an actual position deviates from a predetermined position at a bottom or a top dead center. SOLUTION: A rod-shaped member 7 connected with a ram 2 has alternative north and south magnetized regions at a constant distance along a longitudinal direction and extends through a detection head 12 having a ring coil. When a relative motion takes place between the rod-shaped element 7 and the detection head 12, an alternative electric current is generated in the detection head 12 and it is transmitted to an electronic control unit 13 as a signal, then this measured value is compared with a predetermined value via a line 17. According to this result, the control unit 13 sends a signal with which a height position of the ram 2 is adjusted via a line 18 to a positioning device 11.  A height adjustment device of the ram 2 is given where the detection of the distance between two tools for adjusting a bottom dead center which is important for getting preciseness of workpieces is unnecessary.

Title: Intake air control device for rotary piston engine
Inventor: TSUYUKUCHI MICHIYASU
IPC: F02B53/06
Filed: 1987-02-07
Abstract: PURPOSE:To prevent the reduction in output due to the deficiency of intake air quantity, by providing a timing valve which opens or closes the intake air passage for each cylinder, and further by operating so as to close the timing valve for the cylinder in which intake air flows for a prescribed time at the initial stage of inflow. CONSTITUTION:Into a control circuit 29, detected signals such as those of throttle opening, engine speed, turning angle of an eccentric shaft, or the like are input, and when it is in a pumping-loss control region, a control valve 20 is brought into a NON- advance D condition via a advancer 23, and a negative pressure is introduced into an actuator 28 by changing over a threeway solenoid 31 to open a communicating valve 27, so that the pumping loss control can be carried out by communicating neighbouring cylinders. In other words, a spitting preventive valve 21 is closed to prevent the spitting to be caused in the cylinder on the side to which intake air flows through a communicating passage 26. In this case, although the opening period of the control valve 20 becomes short, since the required intake air quantity is relatively less in a partial load region, the required air quantity can be sufficiently maintained. Further, when it is not in a pumping-loss control region, the communicating pipe 27 is closed via the three-way solenoid 31 and the actuator 28.

Title: Blade tip for throw-away type drill
Inventor: NOGUCHI KAZUO
IPC: B23B51/00
Filed: 1990-02-05
Abstract: PURPOSE:To manufacture a small diameter drill without use of screws and improve the workability and productivity of the drill by fixing a blade part to a shank part by resiliency generated by motion of facing surfaces of a slit formed in a held part. CONSTITUTION:When a blade part 31 is fitted in the direction of an illustrated arrow, facing surfaces of a slit 34 move relatively to each other by wedge action by angle theta1 of taper parts 31b to push a held part 31a to be narrower, and by further fitting it in, the upper end surfaces of holding parts 33a, 33b are applied to the right and left lower end surfaces of the blade part 31 to be fixed. By setting an angle theta2 to make taper parts 31c of the held part 31a parallel to each other and make the contact area of the holding parts 33a, 33b with both side end surfaces the maximum in this condition, the blade part 31 is jointed with and fixed to the shank part 32 by friction force. Because the upper end surfaces of the holding parts 3a, 33b are applied to the blade part 31, in addition, positioning of the blade part 31 to the shank part becomes secure.

Title: Light image displacement detector
Inventor: UTAGAWA TAKESHI
IPC: G01B11/00
Filed: 1979-03-09
Abstract: PURPOSE: To judge what degree of phase change the displacement of a light image causes, by multiplying the outputs of the photoelectric units of a photoelectric unit array position-shifted by one photoelectric unit, by vectors of sequentially different phases, summing up the multiplied factors and comparing the phase difference between the sums.  
     CONSTITUTION: A vector making circuit 3A multiplies the outputs V 1 WV 8  of photoelectric units P 1 WP 8  of a photoelectric unit array 1 and those V 9 WV 16  of its other photoelectric units P 9 WP 16  by vectors of sequentially defferent phases. An addition circuit 5A sums up these multiplications and produces an addition output of amplitude VA and phase ϕA. Another vector making circuit 3B multiplies the outputs V 2 WV 9  of one-position-shifted photoelectric units P 2 WP 9  and those V 10 W V 17  of other one-position-shifted photoelectric units P 10 WP 17  by the same vectors as the circuit 3A. Another addition circuit 5B sums up the latter multiplications and produces an addition output of amplitude VB and phase ϕB. The phase difference ϕA-ϕB between the outputs VA, VB is determined by a phase difference measuring unit 7. The phase ϕA changes depending on the displacement of a light image. It can be judged whether the phase ϕA has a prescribed relation to the displacement to the light phase.

Abstract: PROBLEM TO BE SOLVED: To provide a multi-dimensional data processing method suitable for obtaining data at a high speed in multi-dimensional retrieval by using a set of the coordinate values of a dimension whose coordinate values provided in the successively retrieved plural data are successive and determining a storage position inside a data storage area. SOLUTION: A multi-dimensional coordinate setting processor 103 transforms the attributes of inputted multi-dimensional data to multi-dimensional coordinates 113.

A storage position decision processor 106 determines a storage position 120 by using a storage area number 119 which is the same information as the storage area number 118 and the successive dimension coordinates 117. A data storage processor 107 stores the data at the storage position 121 which is the same information as the storage position 120.

Title: Method for orientating magnetic field of magnetic disk
Inventor: SAKAGUCHI ISAO
IPC: G11B5/845
Filed: 1985-02-14
Abstract: PURPOSE:To improve a polygonal ratio and to obtain a flat coated film surface by providing fixed and rotating plates holding a magnet at both surfaces of a magnetic disk and forming an arbitrary magnet array corresponding to the dried state of a thin film applied to the surface of the disk. CONSTITUTION:After the magnetic disk 1 loaded on a spindle 2 is coated with a magnetic point in a coating station, it is moved to an orientation station in the non-dried state as it is loaded on the spindle 2. Then it is rotated in the direction of an arrow 9, and plates 5 and 6 holding magnets 3 and 4 are rotated. While the plates 5 and 6 are rotating, they move so as to approach to the disk 1, and stop by holding the regulated distance with respect to the coated film surface of the disk 1. The plate 6 is jointed to a motor 8 through a shaft 7, and by rotating the motor in the direction of an arrow 10 the relative angle of the magnet 4 with respect to the magnet 3 can be arbitrarily changed. Thus the magnet array is controlled in such a way, corresponding to the dried state of the coated thin film, whereby the polygonal ratio can be increased and the coated film surface can be made flat.
